“The Gates” (KOAT-7 9 p.m.) ABC’s going all-out with the summer series stuff. Here, we get to see what “Desperate Housewives” would look like if the housewives were all vampires.

Monday 21

“Inedible to Incredible” (TLC 8 p.m.) Crummy chefs are taught how not to be crummy. Alternate title: TLC’s “What Not to Cook.”

Tuesday 22

“Downfall” (KOAT-7 8:01 p.m.) Players answer questions and try to win prizes. So, what’s the gimmick? This game show is held on top of a 10-story building. The prizes are on a conveyor belt. Take too long to answer the questions and the prizes plunge to their doom. It’s a brilliant combination of “Jeopardy!” and David Letterman’s old “Throwing Things off the Roof” segment. Minus the brilliant.
